Bio engineering breakthrough in Denmark

Brand new research makes BioGasol's cellulosic ethanol process even more competitive.
The Danish biotechnology and engineering company Biogasol has reached a new technology breakthrough in cellulosic ethanol production. An improvement of Biogasol’s unique microorganism makes it possible to increase the ethanol yield by a further 7,5 per cent, which makes Biogasol’s bioethanol even more competitive in comparison to gasoline.

Biogasol develops and markets technologies for cellulosic ethanol production, where lignocellulosic biomasses such as wheat straw, corn stover, garden waste or other organic wastes are converted into bioethanol. Cellulosic ethanol is a sustainable and cost effective alternative to oil derived gasoline. In contrast to the first generation ethanol production, where ethanol is produced from wheat, corn and other food products, the second generation production needs a completely different and new fermentation technology.

In the first generation ethanol plants sugars contained in the biomass, also called C6-sugars, are converted into ethanol by using a conventional yeast fermentation process. The sugars in cellulosic biomasses however consist of C6 sugars and up to 30 to 40 per cent of so called C5-sugars, which can not be converted with yeast types currently available on the market. Biogasol has its own patented microorganims, which are able to convert these difficult C5 sugars into bioethanol.

Biogasol’s microorganism originate from hot springs in Iceland and the aim of BioGasol’s development effort has been to refine this microorganism’s natural ability to convert C5 sugars towards maximum ethanol production.

With the recent achievements BioGasol has developed a completely new biotechnical approach to make the microorganism even more effective. Biogasol is now able to increase the amount of ethanol produced by removing the microorganisms natural ability to produce acetic acid and other bi-products.This technical achievement makes Biogasol’s technology even more competitive in an international market that is asking for technologies for conversion of C5 sugars into bioethanol.
